Normally it's just a nitpick to not have trailing spaces on variables.
However, for some things like mac address, it really matters.
Bunches of buildhw's were failing ansibile because they were passing
"mac address " to linux-system-roles networking and ansible was going
'huh, nope, I can't find that mac address here at all'.
So, just blow all the tailing spaces away to avoid any other variables
that hit this.

In ansible 2.8 the - character isn't supposed to be valid in group names.
While we could override this, might has well just bite the bullet and change it.
So, just switch all group names to use _ instead of -
